Effect of asphaltenes on structure of paraffin particles in crude oil.

Original language description

During the transportation and storage of crude oil at low temperatures, asphaltenes and paraffin compounds leave deposits that can cause problems and are expensive to remove. We investigated the effect of an increased amount of asphaltenes on the contentand the size distribution of paraffin particles in samples of crude oil. Two sets of Azeri Light crude oil samples were used: the one set contained the standard asphaltene content of 0.035 wt.%; the other set was enriched with asphaltenes in propane asphalt form until the final asphaltene content was 0.35 wt.%. Both sets were thermally treated in an autoclave at different temperatures (40, 60, 80, 100 oC) for one hour to eradicate their thermal history. Afterwards, the samples were cooled down to 10 oC, and polarized light microscopy was used to record image data about paraffinic particles present in the samples. Image analysis confirmed our theory that the samples with a tenfold higher asphaltene content had significantly reduced amou
